Help Defend Software Freedom and Rights

Folks often ask us how they can help us defend the software freedoms and rights that copyleft makes possible. There are lots of ways to help and we believe that the entire public can help.

Request Source Code

All versions of the GPL and LGPL allow companies to make an offer for Complete, Corresponding Source (CCS) rather than giving you the CCS outright with the product. Sadly, many companies make an offer with no intention of actually providing that CCS to you. As consumers, you have a right to that source code. Look in every manual and “Legal Notices” section of every product you buy. If you see an offer, follow the instructions and request that CCS! If you don't get it, or they give you the run-around, then report the violation to us!

Reporting GPL Violations To Us

If you are aware of a license violation or compliance issue regarding any copyleft license, such as the AGPL, GPL or LGPL, please contact us by email at <>.

If you think you've found a GPL violation, we encourage you to read this personal blog post by our Policy Fellow, Bradley M. Kuhn, about good practices in discovering and reporting GPL violations.
